Title: Manufacture of modified wood
Inventor: TOMOTA AKIHIKO
IPC: B27K3/34
Filed: 1993-12-03
Abstract: PURPOSE:To maintain functions specific to natural wood such as hygroscopicity and feeling by simple operation with a low production cost obtaining good water repellency by heating wood impregnated with a fluorine containing acrylic resin emulsion. CONSTITUTION:Wood, after being adjusted of its water content, is placed in a container such as an autoclave which is then evacuated. With the reduced pressure kept, a fluorine containing acrylic resin emulsion is injected into the container so that the wood is impregnated with the emulsion. The pressure in the container is restored to the atmospheric pressure, and the wood is taken out and dried to remove water in the emulsion. In the wood thus treated, only the outside surface and the inside vessel surface are coated with the fluorine containing acrylic film, leaving the vessel space unfilled with the emulsion so that enough water repellency can be obtained with a low rate of impregnation.

Abstract: PURPOSE:To conserve energy, prevent damages of a cleaning floor, and reduce noises, by detecting the condition of the floor with the variation of input current of an agitator driving motor according to the load variation and stopping an electric motor-driven fan during halt. CONSTITUTION:A floor nozzle 7 is provided with an agitator 8 and its driving motor 9 which are connected by a belt 10. When the floor nozzle 7 is transferred the increased input current of the driving motor 9 is detected by a detecting circuit 14 for input variation. And by receiving that output, a fan control circuit 12 and a nozzle control circuit 13 raise the input to a motorised fan 1 and a driving motor 9 to a specified value to make a rotary condition suitable for the cleaning. On the other hand, when the floor nozzle 7 stops transferring the decrease of the input current of the driving motor 9 is detected by the detecting circuit 14 for input variation. And by this system, the fan control circuit 12 and the nozzle control circuit 13 reduce the input to the motorised fan 1 and the driving motor 9 or make them zero. Accordingly, in this case, running of the cleaner itself is brought to the stopping state.

Title: Photovoltaic element and power generation system
Inventor: KARIYA TOSHIMITSU
IPC: H01L31/04
Filed: 1992-11-16
Abstract: PURPOSE:To prevent the recombination of optically pumped carrier, and improve open-circuit voltage and the carrier range of positive holes, by a method wherein the band gap of an I-type layer containing silicon atoms and carbon atoms is smoothly changed in the layer thickness direction, and the minimum value is biased in the second P-type layer direction from the center position of the layer thickness. CONSTITUTION:The title photovoltaic element consists of the following; a rear electrode 101, an N-type silicon substrate 102, a first P-type layer 103, an N-type layer 104, an Si layer 105, an I-type layer 106 containing Si and C, a second P-type layer 107, a transparent electrode 108, a collecting electrode 109, etc. Since the position of the minimum value of band gap of the I-type layer is biased toward the second P-type layer side, the electric field of a conduction band is large in the vicinity of the P/I interface of the I-type layer, and therefore, electrons are effectively separated from positive holes. In the I-type layer, the electric field of a valence band is increased toward the I/Si interface, so that the recombination of electrons and holes which are optically pumped in the vicinity of the I/Si interface can be decreased, and the photoelectric conversion efficiency can be improved.
